e Be it known that I, Grunn L. ARDERY, a citizen rof the United States, residing at l/Voonsocket, in the county yof Sanborn and State of South Dakota, have u invented certain new and useful Improvements in a Plionograph Stop, of ywhichl the following is a specification. e I I This invention appertains to phonographs and the like and theV primary object ofthe invention isto-provide novel meansv for bringing about the stopping of the turntable of the phonograph, after the playing of the record. n Y .n Y n Another prime object of the invention is the provision of novel means forreturning the record arm toward the starting point of the record and into engagement with a brake trip, whereby the brake will be set for bringl ing about the stopping of the turntable.

Afurther prime object of the invention is the provision of novel means carried by the outer end of the tone arm including a lifting roller adapted to be preferably sprung into lowered position by a trip member Y carried by the record at the end of the groove there,-y in for lifting the sound box above the surface of the record and for returning the tone arm backv toward the edge V,of the record `'into engagement with the brake trip.v `y

A further prime object of he invention 4ris l the provision of a novel brake carried bythe phonograph and set in operation the forcible engagement of the tone armfthe're-` with.

A Stm further Objet of the invention is y to vprovide a novel phonograph stop of the above character, which will be durable and eflicieiit in use, one that will be ysimple, and easy to manufacture and vone/which can. be placed upon the market and incorporatedv with a phonograph at a minimum-cost. f i

lVith these and other objects vin view, 'theA invention consists thek novel )construe-r tion, arrangement and formationQvof,parte, asf will be hereinafter,l more specifically described, claimed and illustratedhinthe accompanying drawings, in whichfdrawings:

Referring to the drawings in detail,y

wherein similar reference charactersA desig-` nate corresponding parts -throughout the seieral views, the letter A generally indicates a,phonography ofany standard construction and Bfthe improved vstop therefor. v

As. stated `rthe phonograph A is of any preferred type rand embodies they usual Icabinet 10,the centerr pin 11 supporting the turntable 12, over whichis adapted to travel the swinging tone arm 13. The tone arm 13 carries in the usual manner the sound box 1e Vhavingthe ordinaryholder 15,`for the stylus 16. The turntable 12 includes the flat disksli'apedbody plate 17y and the depending annular peripheral flange 18. The a center pin 11 and the turntable 12 are adapted to receive phonograph records C, which y in accordanoey with this invention havek ythe inner "sound groove 19 connected with an annular racegroove20 by means of a connecting way or groove 21.k A radially extending slot 22 is also formed in each record adjacent to the aperturefor receivingthe Y.

center pin 11, kfor a purpose, which will be hereinafter, more fully described.

The improved phonograph. stop B coin` prises the tone army carried lifting device and brake tripv 25; the brake 4:5; and the record carrying trip'O for the tone arin carried lifting meaiisand brake ytrip 25.

The tone arm carried lifting device and brake trip 25 comprises essentially a vertically disposed cylinder 26, which isprovided notches 35 that'the friction roller' or rwheely with -a pivot lug 27 which isadjustably connected through the medium ofYan-utandbolt 23 with a clamp 29. This clainp 29 includes companion jaws 30 *for engaging about the stylus holder 15 .whereby the cylinder can be held in an operative position ifelativeto the sound box and phonograph record C. Slidably mounted within'the-cylinder 26isla plunger 31 rotatably carrying at its lower end a friction wheel 32, thepurp'os'e oflwhlch will be hereinafter more fully described. AThe Aplunger 31 `carries `atdia'nietricall-y opposite pointsoutwardly 'extending gide pins 33 which are mountedin guide slo'yts 34 formed in the'cylinder. The upper-ends of the guide slots 34 terminate-in notch-es'35 making a substantially "bayonet slet larrangement. An expansion spring l36 yis fa'rranged within the cylinder and 'ncrinally Vurges the plunger'downward so as to bring the roller 32 into frictionalcontact with "the record and'to raisethe soundboX 14,-'so ythat the stylus 16 will belifted out ofthe 'fsouild groove and above therecord. lt canfb'e'seren that rby pushingin ntheplunger andft'urning the sameso as to move the lug 33"i'n the 32can be heldin araisedposition 4above"the lower end of the nee'dl'ep'or stylus. /Vhenthe wheel or friction roller'32isinoved toits operative record engaging position,thesainejis disposed at an angleY tothe circuinferen'c'e'jof the record, whereby lthieltonte varin 'will vbe moved toward the periphery 'of the A"record due toltheyrot'ation thereof. iA 'zpivoted vlatch' lever` 37is 'connected by 4ineens y'of `a"?'pi'vot pin 38 toaV suitable lug39carried'by` the cylinder 26 :and the'upp'erend'of this lever enlarged and vnotched toiprovicle a'h'eadiO for engaging one pin 33 fwhen the I'piii's are positioned in the i'iotches 35.

The friction roller 32 which can be paddedr if'so desired, engages the upper surface of the record at an angle, as heretoforestated and effectively lifts the stylus 16 above the record and out of the sound groove. The tone arm will now be moved outward toward the periphery of the record andthe foot 44 will be moved into engagement with the L-shaped lug 58 formed on the-brake trip lever 55. This will rock the brake trip lever 55 and move the arm 56 thereof above and out of the path of the lug 53 carriedpby the brake arm 48. This will permit the sliding of the brake arm 48y under the influence of the spring 52 which will forcibly move the shoe 50 into Acontact with the peripheral anges 18 of the turntable 12 and bring about the stopping thereof. In view of the fact that the lug 44 ofthe arm 43 is positioned a relative great distance in advance of the roller 32, the turntable will be brought to a stop, before the roller rides olf of the turntable, which prevents injury to any of the parts of the phonograph and record.

When a new record is tov be played, the parts of the stop are reset as heretofore described.

Changes in details may be made without departing from the spirit or the yscope of this invention. Y

1. The combination with a phonograph including a cabinet, a turntable, a swinging tone arm, and a sound box, and a record on the turntable, of a stop for the phonograph including a brake for engaging the turntable, a trip lever associated with the brake for normally holding the same from out of engagement with the turntable, means carried by the tone arm for lifting the toney arm above the record and toward the brake trip, means carried by the tone arm lifting means for actuating the brake trip, when Lhe tone arm is moved toward thefbrake trip, means normally holding said tone arm lifting means in an inoperative position, and means disposed adjacent to the inner sound groove of the record for operating said last mentioned means to permit the raising of the tone arm.
